The Lowdown
Alright, let me tell you about the next 16 days at Kohala Lighthouse. Honestly, it’s a tough stretch for paddle surfing. The whole period starts with a lot of cross-shore wind, and the surf is just messy. For the first six days, right through to the end of July 25th, we’re looking at poor surf conditions. The wind is blowing fresh and cross-shore, making the ocean lumpy and choppy. Swell hangs around 5 ft to 6 ft, but it’s mostly short-period ENE windswell, and the energy is only moderate (310 to 336). Not the kind of waves you want to paddle out into.
The real change comes on the 26th of July. That’s when we see a proper long-period groundswell arrive from the east, with a period of 16 seconds and combined energy jumping to strong (1601). The swell is 5 ft. But here’s the catch: the wind is still a fresh cross-shore breeze, and it stays lumpy. The forecast calls it marginal, not terrible but not great either. This is a reef break, so that long-period swell will wrap in nicely, but the wind just won’t cooperate. Still, this is the only window that looks even remotely interesting for a surfer willing to work with the conditions.
From the 27th to the 28th, the swell stays strong with energy in the 1700s and height around 6 ft to 7 ft, but the period drops from 15 to 13 seconds. The wind is still cross-shore, and the water temperature is a warm 80°F. That’s about 0.9°F warmer than normal, so nothing unusual. After the 28th, things drop off fast. Swell shrinks down to 4 ft or less, and the energy fades to moderate. By the end of July and into August, it’s back to poor conditions with small, weak swell and cross-shore wind.
The only standout window is the 26th and 27th of July. The swell is solid, the period is long, and it’s a reef break that handles that kind of energy well. But the wind is the problem. If you’re an experienced surfer who can handle lumpy, cross-shore conditions, that might be your best shot. For everyone else, it’s a waiting game. The setup here is more interesting for kite surfing than paddle surfing for most of this period.

Information about the Kohala Lighthouse Surf forecast
The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
